NovaStar, NN452, Meltblown Non-Woven Production Line, 1600mm Width, 1.5 to 2.0 T/24h Capacity (New)

NovaStar, NN452, Meltblown Non-Woven Production Line, 1600mm Width, 1.5 to 2.0 T/24h Capacity

Description

  1. Equipment Introduction
    1. Process introduction of melt spray non-woven cloth production line: melt jet nonwovens process uses high-speed hot air to draft the thin flow of polymer melt extruded from the nozzle hole of die head.
    2. From this form the ultrafine fiber and condense in the coagulation screen or roller and rely on their own bonding and become nonwoven.
    3. Process standard flow: polymer preparation → melt extrusion → metering pump → melt jet die assembly → melt trickle stretching → cooling → receiving device.
